To all whom it may concern.'

Be it known that l, CHARLES M. S'rn/irroN, a citizen ol.i the United States, residing at Toronto, inthe county oi Jefferson and State of Ohio, have invented certain new and use iul Improvements in. Sewer-Pipes; and' l do declare the following to be a -lull, clear, and exact description of the invention, such as will enable others skilled in the art tok which. it appertains to inalie and use the saine, reference being had to the accompanying drawings, and to the ligures of reference marked thereon, which i'orin a part ol this specification.

My invention relates to improvements in pipe, such as is employed in thc construction of sewers, drains, ctc.

ln the forni of pipe at present employed for such purposes, it is dillicult, if not alA Inost impossible, to properly connect the pipe so thattheir openings will accurately register with one another and thus give an uninterrupted and uniform passage throughout the entire length ot sewer, or drain, con-r structed therefrom.

My invention has for its objects, the. pro vision of a pipe, for such purposes, which is not only capable oi self-centering with one another, to avoid the above dilliculty, but is reinforced throughout its entire lengtln'thus causing it to be less liable to breakage than heretofore.

In the accompanying drawings, l have illus* trated my invention by several views, wherein:

Figure l, is a plan view of my improved ipe. Fig. ll, is an end view thereof, and llig. IH, is a longitudinal sectional View through two of" the pipes as associated in practice, similar portions 'of the pipes being designated by like numerals of reference in the following description.

By further reference to said drawings, it will be observed that the invention resides in thc iorn'iingl of longitudinally disposed plural. ribs l, upon the outer portion of the body 2, of the pipe, said ribs being ol such thickness to project beyond the outer si. face of the pipe proper, as to cause selff-cenm tering when the sniall end ci one is ted into the societ or langed head 3, or" the other, shown at Fig. lll, thus causing the openings oli each pipe 'to accurately register with the other throughout the length oi' the structure, at the saine time leaving available within the golnt lor the usual riding.

lt will Yoe readily apparent that the inven-A` tion described not only has the advantage o reinforcement and ability self-eentering with another, but in consequence el" its soli:- centering it occasions no care in associating thein in the coi'istruction ot a sewer, or drain, lthus saving time.

Having thus shown and described my in* vention, what l cl'aiin as new and` desire to secure hy Letters Patent is:

l. [is a new article of manufacture, sewer pipe having a socket Yformed upon one end and provided With a plurality of longitudinally' disposed. ribs upon its exterior ein tending iroin the or' the socket to the opposite extremity'.

2. As a new article of manufacture, a sewer pipe having a socket formed upon one end and provided with a plurality of longitudinall y and oppositely disposed ribs upon its exterior extending troni. the rear of the socket to the opposite extremity., 'ln testimony whereof, l affix my signature, in presence of two witnesses.
